How the date of the first day of fall is set

Astronomical fall (autumn) in the Northern Hemisphere begins at the September equinox, which falls on September 22 or 23 in most years.

At the September equinox the Sun crosses the celestial equator heading south. From then until March, nights are longer than days in the Northern Hemisphere.

The US Naval Observatory publishes the equinox and solstice times. The times on this page are calculated with Jean Meeus's method and agree with them to within a minute or two.

Also coming up: the first day of winter on Monday, December 21, 2026, Halloween on Saturday, October 31, 2026, and Thanksgiving on Thursday, November 26, 2026.

What time does fall start?

The September equinox comes about six hours later each year and about 18 hours earlier after a leap day: 06:01 UTC in 2027, 11:45 UTC in 2028 and 17:37 UTC in 2029.

In UTC, from 2027 to 2036 it falls on September 23 in three years and on September 22 in seven.

The September equinox comes about six hours later each year until a leap day pulls it back.

September equinox facts

At the September equinox, seen from the equator, the Sun rises due east and sets due west. Because the calendar year and the solar year differ slightly, the equinox can fall anywhere from September 21 to 24.

  • Meteorologists count fall from September 1 instead.
  • In the Southern Hemisphere the September equinox is the start of spring.
